Laser melting: Fewer unknowns in the laser nanosynthesis of composites
Composite particles with submicron sizes can be produced by irradiating a suspension of nanoparticles with a laser beam. Violent physical and chemical processes take place during irradiation, many of which have been poorly understood to date. Recentl.....»»

Christmas comes early for Aeolus with improved laser performance
ESA's wind mission continues to shine as engineers have worked their Christmas magic. With a switch back to its original laser, Aeolus is now shining more than twice as brightly with its best ever performance—just in time for the holidays......»»
Greenland"s glaciers might be melting 100 times as fast as previously thought
A computer model has been created by researchers at the Oden Institute for Computational Engineering and Sciences at The University of Texas at Austin that determines the rate at which Greenland's glacier fronts are melting......»»
Relativistic mirror made of plasma at kilohertz repetition rate
Scientists at the LOA (Laboratoire d'Optique Appliquée) in France succeeded for the first time to drive at a thousand shots per second a so-called plasma mirror in the relativistic regime (i.e., with a laser-field so strong that it hurls the plasma-.....»»
Developing a standoff coherent Raman spectrometer
A novel air-laser-based standoff Raman spectrometer with high temporal and frequency resolutions has been constructed by Yao Fu and colleagues. The device can remotely probe chemical species in real time with high temporal resolution while monitoring.....»»
A birefringence-managed normal-dispersion fiber laser delivering energy-tunable chirp-free solitons
Over the past decades, researchers have demonstrated conventional solitons, stretched pulses, self-similar pulses, and dissipative solitons by managing the dispersion and nonlinearity of fiber lasers. However, new types of robust pulses were less dis.....»»
Impressive mixed-reality laser tag game may be VR’s new ace in the hole
Spatial Ops is Resolution Games' next biggest VR invention, and it works particularly well if you have the space to play it......»»

Fusion energy breakthrough by US scientists boosts clean power hopes
First-ever net-energy gain from fusion raises hopes for zero-carbon alternative. Enlarge / The high-powered Nova Laser before it creates nuclear fusion inside its target chamber at the Lawrence Livermore National Laboratory. (cre.....»»
Researchers shed (laser) light on emerging water treatment technique
Assuring that a growing global population has access to clean water will require new water treatment methods. One of these next-generation methods involves a form of iron called ferrate, which creates fewer toxic byproducts than chemicals like chlori.....»»
Radiation shielding: MAPbI3/epoxy composites exhibit superior performance
Gamma rays can cause serious damage to the human body. Therefore, it is very important to develop gamma-ray shielding materials with excellent radiation shielding properties. To reach this goal, scientists in China invented a lightweight perovskite/e.....»»
Deep-space optical communication demonstration project forges ahead
Researchers report new results from the NASA Deep Space Optical Communications (DSOC) technology demonstration project, which develops and tests new advanced laser sources for deep-space optical communication. The ability to perform free-space optica.....»»
Florida mints radiated as peninsula sank and resurfaced during ice ages, finds study
During the ice ages of the Pleistocene, the Florida peninsula regularly grew to twice its current size as glaciers expanded near the planet's poles, only to be reduced to a series of islands as melting ice returned to the sea during warm periods. All.....»»
Small solar flares in large laser bodies
Using 12 high-powered lasers, researchers recreated small solar flares in order to study the mechanisms behind a fundamental astronomical phenomenon known as a magnetic reconnection......»»
Researchers adapt a Nobel Prize-winning method to design new, ultra-powerful X-ray systems
If scientists want to push the boundaries of, say, an X-ray laser, they may need to create some new technology. But occasionally there's no need to reinvent the wheel. Instead, scientists simply come up with a new way to use it......»»
NASA delivers first flight hardware to ESA for Lunar Pathfinder
NASA delivered the first flight hardware for the Lunar Pathfinder mission to ESA (European Space Agency), which formally accepted the instrument on Nov. 4. NASA's Goddard Space Flight Center in Greenbelt, Maryland, developed the instrument, a laser r.....»»
Improving precision of pressure determination in nanosecond X-ray diffraction experiments
X-ray diffraction measurements under laser-driven dynamic compression allow researchers to investigate the atomic structure of matter at hundreds of thousands of atmospheres of pressure and temperatures of thousands of degrees, with broad implication.....»»
